I usually use ABBYY FineReader 12: http://finereader.abbyy.com/
it works very well if images are in good quality.
At University I had a lot of scanned pages of some books and this software converted in few minutes hundred of pages (just images) in a readle pdf file where it's possible to highlight, search, and underline text.
it uses the technique OCR to recognize words.
Maybe you can try it and if you like Abbyy you can "buy" ( ) this
I have ABBYY 11, it's a good program yeah, but for some reason it opens the images in pretty crappy resolution, and I cant seem to figure out how to improve the quality of the scan
If I could improve the quality it would probably have very few text that would need fixing and I could save it there as plain text (in html or doc) instead of working with big ass .PDF files. But yeah... I need to improve the resolution somehow.
Left ABBYY, upper right PDF output, down right, the original image.
Is it because the images are too wide maybe?
edit: it says 'resolution of source img is too small and the image has been resized to larger'. Then it says 'increase resolution to 300dpi or higher'. But howwwww
If u know how to fix this casso... it would solve everything.
Got that ABBYY for my bookscanner btw, I dont recommend it to anyone else cause its cock-expensive
